A judge ruled Monday there is sufficient evidence to hold Bodhi Tree to stand trial on charges of murder and attempted murder in two separate shootings.

Tree, 28, has pleaded not guilty to a pair of murder charges and an attempted murder charge stemming from the May 15 shooting of Rhett August in Eureka and the fatal May 18 shootings of Christina Schwarz and Alan "Sunshine" Marcet in Arcata. He faces 50 years to life in prison if convicted in the case.

After hearing four days of testimony, Humboldt County Superior Court Judge John Feeney determined Monday that prosecutors presented enough evidence to warrant a trial, and set an Oct. 16 date for Tree to be arraigned again in the case.

Prosecutors allege that Tree shot August on May 15 and then -- about 50 hours later -- gunned down Marcet and Schwarz, a Eureka High School senior, at a house in the 2400 block of Eye Street. He had been released from prison a few weeks earlier after serving 16 months for felony evasion of a police officer.

According to court testimony, Tree was living in a Eureka clean and sober house at the time of the shootings.

Much of Monday's testimony focused on the deaths of Schwarz and Marcet.

Questioned by prosecuting Deputy District Attorney Elan Firpo, Nicholas "Eeyore" Page testified that he was living in the Eye Street house in May, describing it as a party house with frequent visitors and guests.

Page said Tree started coming by the house a few weeks before the shootings, after someone who lived there met him at a local bar and invited him over. Tree had been to the house about a half dozen times, Page said, and usually slept over, passing out in a chair in the living room. Page said he remembers Tree introducing himself as "C-Nasty" when the two met and that Tree didn't seem to think much of women.

Page said he witnessed Tree have between three to 10 negative interactions with women in the Eye Street house.

Page testified that he went to sleep early -- at about 8 p.m. -- on the night of May 17 and noticed Tree was in the garage with about seven or eight other people. Page testified that he was sound asleep at about 2 a.m. when gunshots rang out. After throwing on some clothes, Page said he ran out into the house's living room, where he found Marcet and Schwarz, both lying on the ground bleeding from wounds to their torsos. The witness said he immediately grabbed a piece of fabric and used it to start applying pressure to Marcet's wounds.

Firpo asked if he did anything to Schwarz.

"She was not moving and her eyes were open," Page said. "Basically, Sunshine was showing signs of life and she wasn't. I decided to focus on the one of them I felt I could save."

Eye Street resident Michael Edwards, said he noticed a commotion between 1:30 and 1:45 a.m. on May 18. While the neighborhood includes many college students and noisy evenings aren't unusual, this was different, he said.

"How so?" Firpo asked.

"It was angry," Edwards said, adding that the noise drew him out to his porch, where he saw a man dressed in baggy clothes standing in the street where Eye Street intersects with Todd Court, yelling and stomping in what Edwards described as a "temper tantrum."

Edwards said the man was clearly very upset and outraged, and that he yelled something like: "I hate it when they steal my s

." Seeing that no one else was in the street and the man didn't appear to be harming anyone, Edwards said he went back inside and went to bed.

Another neighbor, Nicholas Hunt, who lives across the street from Edwards, also testified Monday, saying he was on his porch smoking a cigarette at about 1:30 a.m. on May 18 when he noticed someone walk up Eye Street and down the driveway to the house where the shootings took place. Hunt said the man -- who he described as being tall and skinny, wearing a hooded sweatshirt and baggy sweat pants -- appeared to be carrying something, like a sleeping bag or clothes, bundled in his arms.

When arrested later that day, Tree was wearing a dark gray hooded sweatshirt and baggy sweat pants.
